Madison Bumgarner says he's fixed a mechanical issue and is feeling much better than he did during the NLDS and NLCS. The left-hander said the mechanical problems he fell into at end of regular season left him feeling tired, but he thinks it's behind him now. Giants manager Bruce Bochy hasn't committed to re-inserting Bumgarner into the rotation, but the southpaw should be able to help the team in whatever role he's used in if he is indeed mechanically sound again.
